Abstract

A display apparatus has a roll of film with multiple still images disposed along the roll of film. The roll of film is scrollable by one or more electric motors to display one or more of the still images on the roll of film at a visual display location. The display apparatus is capable of oscillating desired images on display at the visual display location so as to attract the eye of the observer.

Claims

1. A display apparatus comprising:

(a) a display structure, having a visual display location for displaying a desired still image;

(b) a roll of film having at least two still images set forth thereon, each image being displayable at the visual display location, the roll of film having a first end attached to a first take-up spool and a second end attached to a second take-up spool;

(c) at least one motor for driving the first take-up spool and the second take-up spool so that the roll of film can be alternatively rolled forwards and backwards between the first take-up spool and the second take-up spool; and

(d) a controller for controlling the at least one motor, the controller being capable of controlling the at least one motor to scroll the roll of film to display a desired image at the visual display location, and the controller being capable of controlling the at least one motor to oscillate an image displayed at the visual image location.

2. The display apparatus of claim 1 wherein the at least one motor comprises a first motor for driving the first take-up spool and a second motor for driving the second take-up spool.

3. The display apparatus of claim 2 wherein the takeup spools are dynamically braked.

4. The display apparatus of claim 1 wherein the display structure has at least two visual display locations.

5. The display apparatus of claim 4 wherein the at least two visual display locations are disposed back-to-back.

6. The display apparatus of claim 1 further comprising an oscillator for oscillating a desired image at the visual display location.

7. The display apparatus of claim 6 wherein the film has a front side upon which images are appended and a back side, and wherein a light source is located within the display structure so as to project light against the back side of the film when the film is displaying a desired image at the visual display location.

8. The display apparatus of claim 1 wherein the roll of film comprises an image marker disposed proximate to each image on the roll of film, and wherein the controller further comprises a sensor for identifying each image on the roll of film by sensing each image marker.

9. The display apparatus of claim 1 wherein the visual display location comprises a lower roller and a spaced-apart upper roller, and wherein the desired image is disposed between the lower roller and the upper roller.

10. The display apparatus of claim 1 further comprising image identifying means for identifying individual images on the roll of film independent of each individual image'"'"'s position on the roll of film.

11. The display apparatus of claim 1 wherein the controller includes a clock and the controller is capable of controlling the at least one motor for the display of images at the visual display location based upon the time of day.

12. The display apparatus of claim 1 wherein the roll of film comprises at least ten still images displayed thereon.

13. The display apparatus of claim 1 wherein the controller is capable of controlling the at least one motor to vertically oscillate an image displayed at the visual image location.

14. The display of claim 1 wherein the display apparatus is affixed to a motor vehicle.

15. The display apparatus of claim 1 further comprising a sensor capable of identifying individual images on the roll of film independent of each image'"'"'s relative position on the film.

16. The display apparatus of claim 1 wherein the controller includes gps information means for determining the location of the display apparatus using a global positioning satellite.

17. The display apparatus of claim 1 wherein the controller includes weather sensor means for detecting weather parameters at the display apparatus.

18. The display apparatus of claim 1 further comprising at least one idler roller disposed in contact with the roll of film between the first take-up spool and the second take-up spool.

19. A display apparatus comprising:

(a) a display structure, having a pair of visual display locations disposed back-to-back for simultaneously displaying a pair of desired still images;

(b) a roll of film having at least ten still images set forth thereon, each image being displayable at the visual display location, the roll of film having a first end attached to a first take-up spool and a second end attached to a second take-up spool;

(c) at least one idler roller disposed in contact with the roll of film, the idler roller being located spaced apart from the first take-up spool and the second take-up spool proximate to the visual display location;

(d) at least one motor for driving the first take-up spool and the second take-up spool so that the roll of film can be alternatively rolled forwards and backwards between the first take-up spool and the second take-up spool;

(e) an image marker disposed proximate to each image on the roll of film;

(f) a controller for controlling the at least one motor, the controller being capable of controlling the at least one motor to scroll the roll of film to display a desired image at the visual display location, the controller comprising a sensor for identifying each image on the roll of film by sensing each image marker, and the controller also being capable of controlling the at least one motor to vertically oscillate an image displayed at the visual image location, the controller further comprising a clock and the controller being capable of controlling the at least one motor for the display of images at the visual display location based upon the time of day;

wherein the film has a front side upon which images are appended and a back side, and wherein a light source is located within the display structure so as to project light against the back side of the film when the film is displaying a pair of desired images at the visual display location.

20. A display apparatus comprising:

(a) a display structure, having a visual display location for displaying a desired still image;

(b) a roll of film having at least two still images set forth thereon, each image being displayable at the visual display location;

(c) scroll means for alternatively scrolling the film forwards and backwards to align a desired image at the visual display location;

(d) control means for controlling the scroll means to align a desired image at the visual display location; and

(e) oscillating means for vertically oscillating an image displayed at the visual image location.
